<FONT color="green">077</FONT>     * which has caused a number of differences to appear. As far as possible this<a name="line.77"></a>
<FONT color="green">078</FONT>     * configuration tries to be lenient and support most of the differences.<a name="line.78"></a>

<FONT color="green">080</FONT>     * &lt;p&gt;<a name="line.80"></a>

<FONT color="green">083</FONT>     * &lt;li&gt;&lt;b&gt;Comments:&lt;/b&gt; The '#' character is also accepted as a comment<a name="line.83"></a>

<FONT color="green">085</FONT>     * &lt;li&gt;&lt;b&gt;Key value separator:&lt;/b&gt; The ':' character is also accepted in place of<a name="line.85"></a>
<FONT color="green">086</FONT>     * '=' to separate keys and values in parameters, for example<a name="line.86"></a>
<FONT color="green">087</FONT>     * {@code var1 : foo}.&lt;/li&gt;<a name="line.87"></a>
<FONT color="green">088</FONT>     * &lt;li&gt;&lt;b&gt;Duplicate sections:&lt;/b&gt; Typically duplicate sections are not allowed,<a name="line.88"></a>
<FONT color="green">089</FONT>     * this configuration does however support this feature. In the event of a duplicate<a name="line.89"></a>
<FONT color="green">090</FONT>     * section, the two section's values are merged so that there is only a single<a name="line.90"></a>
<FONT color="green">091</FONT>     * section. &lt;strong&gt;Note&lt;/strong&gt;: This also affects the internal data of the<a name="line.91"></a>
<FONT color="green">092</FONT>     * configuration. If it is saved, only a single section is written!&lt;/li&gt;<a name="line.92"></a>
<FONT color="green">093</FONT>     * &lt;li&gt;&lt;b&gt;Duplicate parameters:&lt;/b&gt; Typically duplicate parameters are only<a name="line.93"></a>
<FONT color="green">094</FONT>     * allowed if they are in two different sections, thus they are local to<a name="line.94"></a>
<FONT color="green">095</FONT>     * sections; this configuration simply merges duplicates; if a section has a<a name="line.95"></a>
<FONT color="green">096</FONT>     * duplicate parameter the values are then added to the key as a list.&lt;/li&gt;<a name="line.96"></a>

<FONT color="green">099</FONT>     * &lt;p&gt;<a name="line.99"></a>
<FONT color="green">100</FONT>     * Global parameters are also allowed; any parameters declared before a section<a name="line.100"></a>
<FONT color="green">101</FONT>     * is declared are added to a global section. It is important to note that this<a name="line.101"></a>

<FONT color="green">103</FONT>     * &lt;/p&gt;<a name="line.103"></a>
<FONT color="green">104</FONT>     * &lt;p&gt;<a name="line.104"></a>

<FONT color="green">161</FONT>     * split the key from the value. Therefore the first property definition in this<a name="line.161"></a>
<FONT color="green">162</FONT>     * section has the key {@code passwd} and the value {@code abc=def}.<a name="line.162"></a>
<FONT color="green">163</FONT>     * This default behavior can be changed by using quotes. If there is a separator<a name="line.163"></a>
<FONT color="green">164</FONT>     * character before the first quote character (ignoring whitespace), this<a name="line.164"></a>
<FONT color="green">165</FONT>     * character is used as separator. Thus the second property definition in the<a name="line.165"></a>

<FONT color="green">170</FONT>     * Internally, this configuration maps the content of the represented ini file<a name="line.170"></a>

<FONT color="green">172</FONT>     * &lt;ul&gt;<a name="line.172"></a>
<FONT color="green">173</FONT>     * &lt;li&gt;Sections are represented by direct child nodes of the root node.&lt;/li&gt;<a name="line.173"></a>
